Abstract
A carbon-rich zirconia-silica sol is prepared by the steps of dissolving zirconyl nitrate hydrate in absolute ethanol, mixing the solution thus obtained with a silicon alkoxide, and mixing the latter solution with a polyelectrolyte. The resulting carbon-rich sol/polyelectrolyte mixture can be employed to coat continuous fiber tow or filaments, to make nanosized zircon powder and to make a porous zircon membrane material.
